謝謝，自從黑屏以後EPC燈就不再亮了，以下是AI的解釋

But I got throttle body replaced. The dealer even returned the old throttle body inside a box (I think they wanted to prove they did the job. The EPC lights disappear and restarted to light 1 weeks later. It became more frequent to light on until the screen was dead and then it disappeared again. At the meanwhile I could smell some burning things.

 

The sequence you describe suggests two separate but possibly overlapping issues:

• EPC light recurrence: Even after throttle body replacement, EPC can re?appear if there are faults in the wiring harness, pedal sensor, brake switch, or ECU. A throttle body replacement alone doesn’t always resolve the root cause.

• Burning smell: This points to an electrical overload or short circuit. If wiring behind the dash or stereo was overheating, that could explain both the smell and why the touchscreen/charger went dead.

• Screen failure timing: The fact that the EPC light stopped showing once the screen died suggests the failing head unit or its wiring may have been drawing excessive current, interfering with other electronic signals.

• Risk: Burning smells mean insulation or wiring may have melted — this is a safety hazard and can cause intermittent faults across multiple systems.

Closure: The EPC light itself isn’t caused by the touchscreen, but a shared electrical fault or short could explain why both the EPC and infotainment acted up together. At this point, the safest move is to have the car’s wiring harness and fuse panel inspected for overheating or shorts before installing a new stereo.

Would you like me to outline a step?by?step diagnostic sequence (fuse check, harness inspection, voltage test) so you can confirm whether the burning smell came from the infotainment wiring or another circuit?
